Retro Depot is happy to announce that the G80-S prototyping boards have arrived. They’ll be added to the store in a day or two.
So far everything looks good. Although we would suggest that you use extra tall stackable headers. Otherwise clearance may be an issue. But your particular setup may give varying results.
These boards feature breakouts for both the z80 bus as well as the PIO ports, a location for a 1117 Regulator (for 3.3v source), power indicator LED, Micro SD location with breakout (including spots for 1208 capacitors), and just over 1000 pads in a standard .100” grid.
